NSURLResponse-如何获取状态码? [英] NSURLResponse - How to get status code?

问题描述

我有一个简单的NSURLRequest:

I have a simple NSURLRequest:

[NSURLConnection sendAsynchronousRequest:myRequest queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
    // do stuff with response if status is 200
}];

如何获取状态码以确保请求正常?

How do I get the status code to make sure the request was ok?

推荐答案

从响应中删除NSHTTPURLResponse的实例，并使用其statusCode方法.

Cast an instance of NSHTTPURLResponse from the response and use its statusCode method.

[NSURLConnection sendAsynchronousRequest:myRequest queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
    NSHTTPURLResponse *httpResponse = (NSHTTPURLResponse *) response;
    NSLog(@"response status code: %ld", (long)[httpResponse statusCode]);
    // do stuff
}];
